What is TISAX?

TISAX (Trusted Information Security Assessment Exchange) is the information security assessment and exchange mechanism developed specifically for the automotive industry. It was created by the German Association of the Automotive Industry (VDA) and is governed and operated by the European Network Exchange (ENX) Association.

As vehicle manufacturers and suppliers became increasingly dependent on complex digital ecosystems, connected technologies, shared intellectual property, and global supply chains, the automotive sector required a standardized method for assessing and demonstrating information security maturity across organizations. TISAX was developed to address this need.

Unlike traditional certifications, TISAX is not a standalone security framework. Instead, it is an assessment and exchange mechanism based on the Information Security Assessment (ISA) catalog, which incorporates requirements from ISO/IEC 27001 and adds automotive-specific controls addressing areas such as prototype protection, information security, data protection, and third-party security management.

TISAX is widely required throughout the automotive supply chain and is commonly requested by:

• Automotive manufacturers (OEMs)
• Automotive suppliers and sub-suppliers
• Engineering service providers
• Research and development organizations
• Software development companies supporting automotive projects
• Cloud service providers and technology vendors serving automotive clients
• Organizations handling prototype vehicles, designs, or confidential automotive information

Many major automotive manufacturers require suppliers and service providers to obtain a TISAX assessment before engaging in business relationships or gaining access to sensitive information.

TISAX also supports compliance efforts related to various security and privacy regulations and standards, including:

• ISO/IEC 27001
• ISO/IEC 27701
• General Data Protection Regulation (GDPR)
• NIS2 Directive
• Automotive cybersecurity initiatives
• Supply chain security requirements
• Third-party risk management programs

TISAX Assessment Objectives

Organizations are assessed against one or more assessment objectives depending on the type of information they process:

• Information Security
• Prototype Protection
• Data Protection
• Confidential Information Handling
• High Availability Requirements

Recent Updates

The TISAX program is continuously updated through revisions to the ISA catalog. The latest ISA versions have introduced increased focus on:

• Cloud security governance
• Supply chain and third-party security
• Secure software development practices
• Data protection controls
• Cyber resilience and operational security
• Alignment with evolving automotive cybersecurity requirements

Organizations pursuing TISAX should monitor updates issued by the ENX Association and VDA to ensure ongoing compliance with the latest assessment criteria.

What Are the Requirements for TISAX?

To participate in TISAX, organizations must establish and maintain a comprehensive information security management program aligned with the ISA catalog requirements.

Basic Organizational Requirements

Organizations typically need to:

• Define and maintain an information security management system (ISMS)
• Identify and classify information assets
• Conduct risk assessments
• Implement security controls based on identified risks
• Establish security policies and procedures
• Define roles and responsibilities for information security
• Implement employee security awareness programs
• Monitor security performance and compliance
• Manage suppliers and third-party risks
• Establish incident response and business continuity processes

Core Control Domains

The ISA catalog evaluates controls across several key domains, including:

• Information Security Management
• Human Resource Security
• Asset Management
• Access Control
• Cryptography
• Physical Security
• Operations Security
• Communications Security
• Supplier Management
• Incident Management
• Business Continuity
• Compliance Management
• Data Protection
• Prototype Protection

Steps to Obtain a TISAX Label

1. Register with the ENX Portal.
2. Determine the required assessment objectives and assessment level.
3. Define the scope of the assessment.
4. Conduct an internal readiness assessment and gap analysis.
5. Implement required security controls.
6. Perform risk assessments and remediation activities.
7. Select an accredited TISAX audit provider.
8. Undergo the formal assessment.
9. Address identified findings.
10. Receive and publish the TISAX label through the ENX platform.

Assessment Levels

TISAX assessments are performed at different Assessment Levels (AL) based on risk and information sensitivity:

• AL1 – Self-assessment
• AL2 – Plausibility review by an accredited assessor
• AL3 – Comprehensive on-site assessment and verification

The required level is generally determined by the automotive customer requesting the assessment.

Governing Organizations

The TISAX ecosystem is managed by:

• ENX Association (Program Operator)
• VDA (German Association of the Automotive Industry)
• Accredited TISAX Assessment Providers

These organizations define the assessment methodology, maintain assessment requirements, and authorize qualified auditors.

Why Should You Be TISAX Compliant?

TISAX compliance provides organizations with both business and security advantages.

Business Benefits

1. Access to Automotive Customers

Many automotive manufacturers and Tier 1 suppliers require a valid TISAX label before sharing sensitive information or awarding contracts.

2. Competitive Differentiation

TISAX demonstrates a recognized level of security maturity, helping organizations stand out during procurement and vendor evaluations.

3. Reduced Customer Audit Burden

A single TISAX assessment can often satisfy multiple customer security assessment requirements, reducing the need for repetitive audits and questionnaires.

4. Increased Customer Trust

Customers gain confidence that sensitive information, intellectual property, and personal data are being adequately protected.

5. Stronger Security Posture

Organizations improve visibility into risks, strengthen governance processes, and reduce exposure to cyber threats.

6. Risks of Non-Compliance

Organizations that fail to meet TISAX requirements may face:

• Loss of business opportunities within the automotive industry
• Inability to participate in supplier programs
• Increased customer audit requests
• Delays in onboarding and contracting processes
• Greater exposure to cyber incidents and data breaches
• Reputational damage
• Potential regulatory consequences when security or privacy obligations are not adequately addressed

As the automotive industry continues to increase cybersecurity expectations across its supply chain, TISAX has become a critical business requirement rather than simply a security best practice.

How to Achieve TISAX Compliance with Centraleyes

Centraleyes simplifies and accelerates TISAX readiness by providing a centralized platform for managing information security, risk, compliance, and third-party security requirements. Organizations can assess their current security posture against TISAX requirements through automated assessments and maturity evaluations, identify compliance gaps and remediation priorities through automated gap analysis, and continuously manage risks with automated risk identification, scoring, treatment planning, and monitoring.
